Arrangements described herein relate to generating a user unavailability alert in a collaborative environment. A user may encounter a situation that influences the user to focus attention away from a subject of a collaborative session. For example, the user may be assigned an action unrelated to a current collaborative session, called home, or otherwise be distracted. The user can enter a user input indicating that the user is to be unavailable, for example by selecting a panic button. When the user indicates such, the user's activity in a collaboration session can be analyzed to identify whether any pending actions are allocated to the user which relate to other people identified by the user's participation in the collaborative environment. If so, a message can be communicated to one or more other participants in the collaborative environment indicating the unavailability of the user.

FIG. 1 is a block diagram illustrating a system (hereinafter “system”) 100 for generating a user unavailability alert in a collaborative environment in accordance with one embodiment disclosed within this specification. As used herein, the term collaborative environment means an environment in which users collaborate via one or more communication networks. Aspects of a collaborative environment may include, but are not limited to, electronic mail (email), text messaging, instant messaging (IM), telephone calls, telephone conferences, video conferences, web conferences, social media (e.g., via social networking sites), calendaring applications, and/or the like. Within a collaborative environment, a user 105 may participate in one or more collaborative sessions. Each collaborative session may include user participation in one or more aspects of the collaborative environment. Further, each collaborative session can pertain to a particular subject, for example a project. One or more users can be assigned actions (e.g., tasks) pertaining to the particular subject. Further, one or more participants may be assigned responsibility for monitoring the progress of other participants on assigned actions (e.g., pending actions), or may otherwise be impacted by the progress of other participants on assigned actions.

As used herein, the term “participant” means a person (i.e., human being) who participates in one or more collaborative sessions. As used herein, the term “user” also means a person (i.e., human being) who participates in one or more collaborative sessions. Herein, the term “user” is used to distinguish a particular person who participates in one or more collaborative sessions from one or more other people who participant in one or more collaborative sessions. Thus, the term “user” means a particular participant.

The system 100 can include a collaborative information system (CIS) 110.

The collaborative information system 110 can include a message distributor 115, a collaboration information collector (CIC) 125 and a collaboration information buffer (CIB) 130. The CIB 130 can be configured to collect collaborative information related to use by a user 105 of various collaboration media, such as IMs, electronic mail (email), calendaring entries, social media, conferencing media and the like. In this regard, the CIB 130 can include various modules for collecting such information, for example an IM information module 132, an email information module 134, a calendaring information module 136, a social media information module 138, a conferencing information module 140, a collaborative platform information module 142, and the like.

The system 100 further can include collaboration media clients 150 which store/record collaboration media, or have access to the stored/recorded collaboration media, and from which the CIB 130 collects the collaborative media. In illustration, the collaboration media clients 150 can include an IM client 152, an email client 154, a calendaring client 156, a social media client 158, a conferencing client 160, a collaborative platform client 162, and/or the like. The collaborative platform client 162 can be configured to include email, calendaring, social media, conferencing, unified messaging and/or other functionality. In this regard, the collaborative platform client 162 can be included in addition to, or in lieu of, one or more of the clients 152-160. Examples of a collaborative platform client 162 include, but are not limited to, IBM® Real-time Collaboration, IBM® Lotus® Connections, and the like. (IBM and Lotus are trademarks of International Business Machines Corporation in the United States, other countries, or both).

The clients 152-162 can be implemented as one or more applications executed by the system 100. In one example, one or more of the clients 152-162 can be implemented as a web browser that accesses one or more suitable web servers that provide and receive from the system 100 corresponding data. In this regard, the web browser can be executed to operate as an IM client session, an email client session, a calendaring client session, a social media session, a conferencing session and/or the like. The present arrangements are not limited to use of a web browser, however. For example, the email client 154 and the calendaring client 156 can be implemented by an application configured to operate as a client for such operations. In another example, the conferencing client 160 can be a component of a telephone system, such as a VoIP telephone system, and may include telephone call recording capabilities. Still one or more applications can be configured to operate as clients as described herein and the present arrangements are not limited in this regard.

In operation, the user 105 can enter a user input into the system 100 indicating that the user 105 will be unavailable. For example, via a user interface (such as a graphical user interface (GUI)) one or more controls, such as icons, buttons, menu items, widgets or the like, can be presented to the user 105 on a display, and configured to receive the user input. In another arrangement, one or more controls, such as one or more buttons, keys, or the like, can be provided on a mouse, track pad, touch pad, keyboard, display or other device and the system 100 can be configured to recognize a selection by the user of such control(s) indicates that the user 105 will be unavailable. In response to the user input, a user unavailability alert in the collaborative environment can be generated, for example as one or more messages, which are described herein.

When the user decides that the user will become unavailable, the user 105 can select any one or more of the described controls to indicate the user's unavailability. In one arrangement, the control can be a panic button selectable by the user 105 to indicate that the user 105 is unavailable until further notice. Other than selection by the user, the panic button need not require further user input. In another arrangement, when the user 105 selects the control, the user 105 can be prompted to indicate how long the user 105 estimates that he/she will be unavailable, a data and/or time when the user 105 expects to again be available, etc.

When the user 105 selects the control to indicate the user's unavailability, the CIC 125 can initiate the CIB 130 to collect collaboration media from the various clients 152-162 and store, at least temporarily, the collaboration media in the respective modules 132-142. As used herein, the term “collaboration media” means any media generated during a collaboration session, for example, text, audio, video, images, slides, and so on. The collaboration media can be media from collaborative sessions in which the user 105 participated, for example within the last hour, the last day, the last week, the last month, the last year, etc. In illustration, if the user 105 participated in a particular collaboration session in the last day, all media from that collaboration session can be retrieved, or the CIB 130 can filter the collaboration media to only retrieve recent collaboration media, for example within the last day, the last week or the last month. The CIB 130 also can filter collaboration media to ignore off topic media and/or previously sent unavailability messages, which will be described herein.

The CIC 125 can access the collaboration media from the CM 130 and process such collaboration media to generate statistical data based upon the collaboration media and/or the user's activity (e.g., participation) in the collaboration sessions. When processing text media (e.g., IMs, emails, calendaring information, etc.), the CIC can apply text analysis to generate the statistical data. When processing audio collaborative media, the CIC 125 can apply speech-to-text analyses to generate a transcript of the audio which may be processed to generate the statistical data. When processing video collaborative media and/or collaborative media that contain still images, the CIC 125 can apply image recognition to generate related data, and process the related data to generate the statistical data.

The statistical data can identify collaboration sessions in which the user 105 participated, those collaboration sessions in which the user 105 participated heavily, those collaboration sessions in which the user 105 participated moderately, those collaboration sessions in which the user 105 participated minimally, and so on. The statistical data also can identify relative percentages of the user's total collaboration activity with regard to the user's participation in specific collaboration sessions. Further, based on the analysis of the collaboration media, the CIC 125 can identify other participants who participated in the collaboration sessions, any actions allocated (e.g., assigned) to the user 105, actions allocated by the user 105 to one or more other participants, the status of such actions, and so on. Such actions may be pending actions or actions that have been completed. Still, the CIC 125 can generate any other data relevant to the user's participation in the collaborative sessions and the present arrangements are not limited in this regard.

In one aspect, to determine the status of actions allocated to the participant or allocated to other participants, the CIC 125 can determine an amount of work completed on such actions. For example, the CIC 125 can determine a scheduled length of an action, the amount of work required to complete the action, the amount of work already completed on the action, and do on. In one arrangement, the CIC 125 can interface with a collaboration tool, for example IBM® Rational Team Concert™, to obtain such information related to the allocated actions. (Rational Team Concert is a trademark of International Business Machines Corporation in the United States, other countries, or both).

Further, the CIC 125 can determine whether other participants in the collaborative sessions may be impacted by, or otherwise should be notified of, the user's unavailability. If so, the CIC 125 can interface with the message distributor 115 to generate and communicate one or more messages to such participants via the collaboration media clients 150 indicating the user's unavailability. In illustration, the message distributor 115 can send one or more IMs via the IM client 152, one or more emails via the email client 154, add/update one or more calendar entries via the calendaring client 156, send one or more messages via the social media client 158, send one or more messages via the conferencing client 160, and so on. In one arrangement, the type of client 152-162 selected for sending the message(s) can be based on the type of client used by the user 105 when collaborating with the other participant(s) when the action was assigned to the user 105.

For example, the user 105 may select the control via the GUI indicating that the user 105 is unavailable. In response, the CIC 125 can analyze the collaboration session media and identify information indicating the user 105 was allocated an action to be completed this afternoon. The CIC 125 also may determine that whether action is yet completed. If the user 105 did not indicate, via the control, that the user 105 will return this afternoon, and the action is not yet completed, the CIC 125 automatically generate and can send one or more messages to the participant who allocated to action to the user 105, and/or to one or more other participants collaborating in the collaboration session in which the action was assigned, indicating that the action allocated to the user 105 may not be completed as original scheduled. Accordingly, the participants will be apprised that the user 105 may not be able to complete the task by the target date/time. An example of such message may include a statement generated on behalf of the user 105, for example, “Due to unforeseen circumstances, I am unable to complete the assigned task I promised for today.”

If when selecting the control the user 105 indicated a date/time when the user 105 again will be available, the CIC 125 can estimate an amount of work left to be completed on the task, for example by comparing the amount of work completed to the anticipated amount of work required for the task, and estimate when the user 105 should be able to complete the allocated action. The CIC 125 can communicate with the message distributor 115 to include in the message(s) that are sent the estimated date/time when the action will be completed by the user 105. For example, the message(s) may include a statement “Due to unforeseen circumstances, I am unable to complete the assigned task I promised for today. I do, however, believe I can complete the task by Monday.”

Further, the CIC 125 can estimate a probability of the action being completed by a certain time/date. For example, if today is Thursday, and the user 105 selects the unavailability control, and a pending action to be completed by the user is not due until next Monday, the CIC 125 can evaluate the amount of work necessary to complete the task, an amount of work already completed on the task, and the amount of other actions the user 105 is tasked with for Friday and Monday. When evaluating the other actions the user 105 is tasked with, the CIC 125 can identify a priority of the present action and compare the priority of the present action with the priorities of the other actions. If the present action has higher priority than the other actions, the CIC 125 can automatically reschedule the due dates/times of the other actions. If the present action does not have higher priority, the CIC 125 can schedule the present action around the other actions. Based on this information, the CIC 125 can estimate a probability percentage (e.g., 60%) that the user will be able to complete the task by Monday. This probability percentage can be indicated in the message(s) that are sent to the other participant(s). For example, the message(s) may include a statement “Due to unforeseen circumstances, I am unable to complete the assigned task I promised for today. I believe the probability I will complete the task by Monday is 60%.”

The CIC 125 can estimate the probability percentage based on a number of parameters. For example, the CIC 125 can process a parameter representing a typical duration of unavailability, the position of the day when the user 105 becomes unavailable with respect to the weekend (e.g., the probability the user 105 still being unavailable on Monday when the unavailability period begins on Friday), and so on. Of course, if the user specifies how long the user anticipates he/she will be unavailable when selecting the unavailability control, the CIC 125 can process this data in lieu of a typical duration of unavailability.

Further, if the one or more other actions are rescheduled to accommodate rescheduling of the present action, the CIC 125 can implement the processes described herein to identify one or more other participants who should be notified of such rescheduling, and interface with the message distributor 115 to generate one or more message(s) to the other participant(s) indicating rescheduling of such tasks, the probability of such tasks being completed at the rescheduled date(s)/time(s), and so on.

As noted, in some instances, a collaboration session may take place using audio information, for example in a teleconference or web conference. In such instances, the message(s) can be provided as audio information. For example, text to speech synthesis can be applied to message text that is automatically generated by the CIC 125 to generate a corresponding audio message. The audio message can be sent to other participant(s) via one or more clients 152-162 suitable for communicating audio messages. Further, the user's telephone system can be automatically configured to monitor incoming calls from the other participant(s), and when such a call is received, present (e.g., telephonically communicate) the audio message as a call answer message (e.g., using a voice mail system). A contact list maintained for the user 105 can indicate contact names, telephone numbers, extension numbers, email addresses, IM identifiers, IP addresses, and the like, and can be accessed by the CIC 125 to determining whether an incoming call is from another participant in a collaborative session. In this regard, the audio message can be personalized for the caller.

The CIC 125 can initiate collection of collaboration media into the CIB 130, processing of such media, and generating of the message(s) in real time when the user 105 selects the unavailability control. As used herein, the term “real time” means a level of processing responsiveness that a user 105 or system senses as sufficiently immediate for a particular process or determination to be made, or that enables the processor to keep up with some external process. Further, the CIC 125 can implement any suitable algorithms to arrive at any statistical determinations made by the CIC 125.

In an arrangement in which the user 105 selects the unavailability control, but does not indicate when the user 105 again will become available, the CIC 125 can monitor the availability status of the user 105. For example, the CIC 125 can monitor for a selection by the user 105 of a control in the GUI indicating that the user is available, or monitor for an event related to the user 105 logging into the system 100. When the user 105 logs into the system, the CIC 125 can prompt the user to indicate whether the user 105 wishes to change his/her status to being available, or to keep the status as unavailable, and receive a corresponding response from the user.

While the user 105 remains unavailable, and has not indicated when he/she will again be available within a specified period of time subsequent to initially indicating the user unavailability, the CIC 125 can periodically initiate the CIB 130 to update the collaborative session information maintained in the modules 132-142, and the CIC 125 can analyze the updated session information. Further, the CIC 125 can interface with the message distributor 115 to send updated messages indicating the user 105 still is unavailable, provide updated estimates of when (e.g. time and/or date) assigned actions will be completed, etc. The period between updates can be, for example one or more hours, one or more days, one or more weeks, etc. When the CIC 125 detects that the user 105 becomes available, the CIC 125 can cease the updates of the session information in the CIB 130, cease further analysis processes on the session information, and cease sending further messages, at least until the user 105 again becomes unavailable, or another participant in the collaborative sessions becomes unavailable.

FIG. 2 is a flow chart illustrating a method 200 of generating a user unavailability alert in a collaborative environment in accordance with an embodiment disclosed within this specification. At step 202, a user input can be received from a user indicating an unavailability of the user. At step 204, responsive to the user input, via a processor, activity of the user in the collaborative environment can be analyzed to identify whether any pending actions are allocated to the user which relate to other people (e.g., other participants) identified by the user's participation in the collaborative environment.

At step 206, responsive to determining at least one pending action is allocated to the user which relates to at least one other person identified by the user's participation in the collaborative environment, a first message can be generated to be communicated to the at least one other person indicating the unavailability of the user. Further, the first message can indicate that a completion time or date of the pending action allocated to the user is affected by the unavailability of the user.

In one arrangement, responsive to determining at least one pending action is allocated to the user which relates to at least one other person identified by the user's participation in the collaborative environment, a probability the user will be able to complete the pending action by an assigned time or date can be automatically determined. In this arrangement, the first message can indicate the probability the user will be able to complete the pending action by the assigned time or date.

In another arrangement, responsive to determining at least one pending action is allocated to the user which relates to at least one other person identified by the user's participation in the collaborative environment, the pending action can be automatically re-scheduled. In this arrangement, a new completion date or time of the pending action allocated to the user can be automatically estimated, for example as described herein, and the first message can indicate the new completion time or date for the pending action. The message further can indicate a probability that the action will be completed at the new completion date or time.

In another arrangement, the first message can be a personalized audio message to be presented to the at least one other person identified by the user's participation in the collaborative environment. The personalized audio message can be telephonically communicated to the at least one other person in response to a telephone call to the user being received from the at least one of the other person.

At step 208, the first message can be communicated to the at least one other person.

At step 210, responsive to determining a user input indicating an availability of the user is not received within a specified period of time subsequent to the user input, a second message to the at least one other person can be generated indicating the unavailability of the user. For example, a new completion time or date of the pending action allocated to the user can be automatically estimated, and the second message further can indicate the new completion time or date. The second message also can indicate the probability of the user completing the allocated action by the new completion time or date.

FIG. 3 is a processing system 300 configured to generate a user unavailability alert in a collaborative environment in accordance with an embodiment disclosed within this specification.

The processing system 300 can include at least one processor 305 (e.g., a central processing unit) coupled to memory elements 310 through a system bus 315 or other suitable circuitry. As such, the processing system 300 can store program code within the memory elements 310. The processor 305 can execute the program code accessed from the memory elements 310 via the system bus 315. It should be appreciated that the processing system 300 can be implemented in the form of any system including a processor and memory that is capable of performing the functions and/or operations described within this specification. For example, the processing system 300 can be implemented as a computer, a workstation, a mobile computer, a laptop computer, tablet computer, a smart phone, a personal digital assistant, a gaming device, an appliance, and so on.

The memory elements 310 can include one or more physical memory devices such as, for example, local memory 320 and one or more bulk storage devices 325. Local memory 320 refers to RAM or other non-persistent memory device(s) generally used during actual execution of the program code. The bulk storage device(s) 325 can be implemented as a hard disk drive (HDD), solid state drive (SSD), or other persistent data storage device. The processing system 300 also can include one or more cache memories (not shown) that provide temporary storage of at least some program code in order to reduce the number of times program code must be retrieved from the bulk storage device 325 during execution.

Input/output (I/O) devices such as a keyboard and/or keypad 330, a display and/or touchscreen 335, a pointing device 340 and/or a network adapter 345. The I/O devices can be coupled to the processing system 300 either directly or through intervening I/O controllers. Modems, cable modems, and Ethernet cards are examples of different types of network adapters 345 that can be used with processing system 300.

As pictured in FIG. 3, the memory elements 310 can store the components of the system 100 of FIG. 1, namely the CIS 110 and the collaboration media clients 150. Being implemented in the form of executable program code, these components of the system 100 can be executed by the processing system 300 and, as such, can be considered part of the processing system 300. Moreover, the CIS 110 and the collaboration media clients 150 are functional data structures that impart functionality when employed as part of the processing system 300 of FIG. 3. In illustration, the CIS 110 and collaboration media clients 150 can be executed by the processor 305 to implement the processes and functions respectively describe herein.

The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures.
